      | The status of this row.
        An entry may not exist in the active state unless all
        objects in the entry have an appropriate value.  No objects
        are required to be written prior to the row being set to
        active(1).  However, all portSelTable entries which are to
        be included in collections on behalf of this
        portSelectGroup, must be completely configured and activated
        before this object is set to active(1), since the associated
        instances of portSelStatus cannot be modified once this
        object has been set to active(1).
        If this object is not equal to active(1), all associated
        data collections shall be deleted (e.g., any associated
        collections in the atmStats, atmHostTable or
        atmMatrixSDTable).
        Note that associated portSelTable and any configured
        collection control entries (e.g., atmHostControlTable) are
        not deleted when this entry leaves the active state. |

      | portSelStatus | .1.3.6.1.4.1.9.10.16.1.1.2.1.4 | 
    
      | The status of this row.
        An entry may not exist in the active state unless all
        objects in the entry have an appropriate value.
        Specifically, an appropriate value for the
        portSelCollectGroup object must be set before this object
        may be set to active(1). An agent may wish to allow
        portSelTable entries to exist which reference non-existent
        portSelGrpTable entries, in order to reduce row creation
        order dependencies.
        All portSelTable entries which are to be included in a
        particular collection (as indicated by the
        portSelCollectGroup object), should be completely configured
        and activated before the associated portSelGrpStatus object
        is set to active(1).  Configuration of a portSelectGroup
        cannot be modified once collections on its behalf have been
        started.
        This object may not be modified if the associated
        portSelGroupStatus in in the active(1) state, indicated by a
        portSelGrpIndex value identical to the value of the
        portSelCollectGroup object in this entry. |

        This control entry may be created and destroyed
        independently of the associated portSelGrpEntry, however its
        associated atmStatsTable can exist only when the
        portSelGrpEntry controlling this collection is active.

      | The number of call attempts detected on all signalled ATM
        connections on behalf of this portSelectGroup collection.  A
        probe should increment this counter each time a connection
        setup attempt (identified with this portSelectGroup) is
        detected. For point-to-multipoint connections, this counter
        is incremented once per counted connection, regardless of

        portSelectGroup collection.  Note that this value includes
        successfully established calls that are currently in
        progress.  A probe should increment this counter each time a
        valid connection (identified with this portSelectGroup) is
        successfully established. For point-to-multipoint ATM
        connections, this counter is incremented once per counted
        connection, regardless of the number of leafs identified in
        the connection. Note that when a point-to-point connection
        setup enters on one port and leaves on another port in the

        the atmHost table.  If an entry is inserted, then deleted,
        and then inserted, this counter will be incremented by 2.
        To allow for efficient implementation strategies, agents may

        resources, in the event the probe must reclaim some
        resources in order to add new entries to an existing
        atmMatrix collection or add new collections of other types.
        If the associated instance of atmMatrixControlStatus object
        is equal to active(1), this object may not be modified. |

        in atmMatrixSDTable and atmMatrixDSTable entries created on
        behalf of this control entry, according to the rules
        specified by the AddressCollectScope textual convention.
        If the associated instance of atmMatrixControlStatus object

      | The total number of events in which cells which should have
        been counted in the associated atmMatrixSDEntry and
        atmMatrixDSEntry, but were dropped by the probe due to lack
        of resources.  Note that this number is not necessarily the
        number of cells or calls dropped; it is just the number of
        times this condition has been detected. |

      | The status of this atmMatrixControlEntry.
        An entry may not exist in the active state unless all
        objects in the entry have an appropriate value.
        Specifically, the associated instances of
        atmMatrixControlMaxDesiredEntries, atmMatrixControlPriority,
        and atmMatrixControlAddrCollectScope objects must be set to
        appropriate values before this object may be set to
        active(1).
        This control entry may be created and destroyed
        independently of the associated portSelGrpEntry, however its
        associated atmMatrixSDTable and atmMatrixDSTable can exist
        only when the portSelGrpEntry controlling this collection is
        active.
        If this object is not equal to active(1), all associated
        entries in the atmMatrixSDTable and atmMatrixDSTable shall
        be deleted. |

      | The number of error-free cells detected on connections in
        which these ATM addresses were identified as the
        transmitting and receiving endpoint addresses.
        Note that for point-to-multipoint connections, an entry is
        created for each root-to-leaf address-pair that exists, and
        each cell sent from the root on a point-to-multipoint ATM
        connection is counted once in each distinct matrix entry. |

        atmMatrixSDDstAddress was identified as the Called Party.
        Note that this value includes calls that are currently in
        progress.  A probe should increment this counter each time a

      | atmMatrixTopNControlIndex | .1.3.6.1.4.1.9.10.16.1.4.4.1.1 | 
    
      | An index that is used to uniquely identify an entry in the
        atmMatrixTopNControlTable.  Each such entry defines one top
        N report prepared on behalf of one atmMatrix entry, which
        must exist before this entry may be created. | 
    
      | atmMatrixTopNControlRateBase | .1.3.6.1.4.1.9.10.16.1.4.4.1.2 | 
    
      | The variable for each atmMatrix entry that the
        atmMatrixTopNEntries are sorted by.
        This object may not be modified if the associated
        atmMatrixTopNControlStatus object is equal to active(1). | 
    
      | atmMatrixTopNControlSClass | .1.3.6.1.4.1.9.10.16.1.4.4.1.3 | 
    
      | The service class for which this topN control entry is
        collecting information in associated atmMatrixTopN reports.
        This object may not be modified if the associated
        atmMatrixTopNControlStatus object is equal to active(1). | 
    
      | atmMatrixTopNControlTimeRemaining | .1.3.6.1.4.1.9.10.16.1.4.4.1.4 | 
    
      | The number of seconds left in the report currently being
        collected.  When this object is modified by the management
        station, a new collection is started, possibly aborting a
        currently running report.  The new value is used as the
        requested duration of this report, and is immediately loaded
        into the associated atmMatrixTopNControlDuration object.
        When the report finishes, the probe will automatically start
        another collection with the same initial value of
        atmMatrixTopNControlTimeRemaining.  Thus the management
        station may simply read the resulting reports repeatedly,
        checking the startTime and duration each time to ensure that
        a report was not missed or that the report parameters were
        not changed.
        While the value of this object is non-zero, it decrements by
        one per second until it reaches zero.  At the time that this
        object decrements to zero, the report is made accessible in
        the atmMatrixTopNTable, overwriting any report that may be
        there.
        When this object is modified by the management station, any
        associated entries in the atmMatrixTopNTable shall be
        deleted. | 
    
      | atmMatrixTopNControlGeneratedReports | .1.3.6.1.4.1.9.10.16.1.4.4.1.5 | 
    
      | The number of reports that have been generated by this
        entry. | 
    
      | atmMatrixTopNControlDuration | .1.3.6.1.4.1.9.10.16.1.4.4.1.6 | 
    
      | The number of seconds that this report has collected during
        the last sampling interval.
        When the associated atmMatrixTopNControlTimeRemaining object
        is set, this object shall be set by the probe to the same
        value and shall not be modified until the next time the
        atmMatrixTopNControlTimeRemaining is set.
        This value shall be zero if no reports have been requested
        for this atmMatrixTopNControlEntry. | 
    
      | atmMatrixTopNControlRequestedSize | .1.3.6.1.4.1.9.10.16.1.4.4.1.7 | 
    
      | The maximum number of host entries requested for this
        report.
        When this object is created or modified, the probe should
        set atmMatrixTopNControlGrantedSize as closely to this
        object as is possible for the particular probe
        implementation and available resources. | 
    
      | atmMatrixTopNControlGrantedSize | .1.3.6.1.4.1.9.10.16.1.4.4.1.8 | 
    
      | The maximum number of host entries in this report.
        When the associated atmMatrixTopNControlRequestedSize object
        is created or modified, the probe should set this object as
        closely to the requested value as is possible for the
        particular implementation and available resources. The probe
        must not lower this value except as a result of a set to the
        associated atmMatrixTopNControlRequestedSize object.
        For example, if the value of atmMatrixTopNControlRateBase is
        equal to atmMatrixTopNCells(1), when the next topN report is
        generated, host entries with the highest value of
        atmMatrixSDCells shall be placed in this table in decreasing
        order of this rate until there is no more room or until
        there are no more matrix entries. Each atmMatrixSDCells
        value is copied to the associated atmMatrixTopNRate object.
        It is an implementation-specific matter how entries with the
        same value are sorted.  It is also an implementation-
        specific matter as to whether or not zero-valued entries are
        available. | 
    
      | atmMatrixTopNControlStartTime | .1.3.6.1.4.1.9.10.16.1.4.4.1.9 | 
    
      | The value of sysUpTime when this top N report was last
        started.  In other words, this is the time that the
        associated atmMatrixTopNControlTimeRemaining object was
        modified to start the requested report or the time the
        report was last automatically (re)started.
        This object may be used by the management station to
        determine if a report was missed or not. | 
    
      | atmMatrixTopNControlOwner | .1.3.6.1.4.1.9.10.16.1.4.4.1.10 | 
    
      | The entity that configured this entry and is therefore
        using the resources assigned to it. | 
    
      | atmMatrixTopNControlStatus | .1.3.6.1.4.1.9.10.16.1.4.4.1.11 | 
    
      | The status of this atmMatrixTopNControlEntry.
        An entry may not exist in the active state unless all
        objects in the entry have an appropriate value.
        If this object is not equal to active(1), all associated
        entries in the atmMatrixTopNTable shall be deleted by the
        agent. | 
    
      | atmMatrixTopNIndex | .1.3.6.1.4.1.9.10.16.1.4.5.1.1 | 
    
      | An index that uniquely identifies an entry in the
        atmMatrixTopNTable among those in the same report.  This
        index is between 1 and N, where N is the number of entries
        in this report.
        Each conversation in the selected atmMatrixSDTable, for the
        report interval, is ranked in descending order of the metric
        identified by the atmMatrixTopNRate object.
        For example, if the value of atmMatrixTopNControlRateBase is
        equal to atmMatrixTopNCells(1), increasing values of
        atmMatrixTopNIndex shall be assigned to entries with
        decreasing delta values of atmMatrixSDCells (for the report
        interval), until index N is assigned or there are no more
        atmMatrixSDEntries. | 
    
      | atmMatrixTopNSrcAddress | .1.3.6.1.4.1.9.10.16.1.4.5.1.2 | 
    
      | The ATM endpoint address identified as the source of the
        traffic measured in this report.
        Note that only 20 octet 'AtmAddr' addresses are collected in
        this table. | 
    
      | atmMatrixTopNDstAddress | .1.3.6.1.4.1.9.10.16.1.4.5.1.3 | 
    
      | The ATM endpoint address identified as the destination of
        the traffic measured in this report.
        Note that only 20 octet 'AtmAddr' addresses are collected in
        this table. | 
    
      | atmMatrixTopNRate | .1.3.6.1.4.1.9.10.16.1.4.5.1.4 | 
    
      | The value of the ranked metric for this conversation, for
        this report.
        If the associated value of atmMatrixTopNRateBase is equal to
        atmMatrixTopNCells(1), then this object is assigned the
        delta value of the atmMatrixSDCells object during this
        report interval.
        If the associated value of atmMatrixTopNRateBase is equal to
        atmMatrixTopNNumCallAttempts(2), then this object is
        assigned the delta value of the atmMatrixSDNumCallAttempts
        object during this report interval.
        If the associated value of atmMatrixTopNRateBase is equal to
        atmMatrixTopNNumCalls(3), then this object is assigned the
        delta value of the atmMatrixSDNumCalls object during this
        report interval.
        If the associated value of atmMatrixTopNRateBase is equal to
        atmMatrixTopNConnTime(4), then this object is assigned the
        delta value of the atmMatrixSDConnTime object during this
        report interval. | 
    
      | atmMatrixTopNReverseRate | .1.3.6.1.4.1.9.10.16.1.4.5.1.5 | 
    
      | The value of the associated metric for this conversation,
        and for this report, but for the reverse direction.
        For example, if the associated value of
        atmMatrixTopNRateBase is equal to atmMatrixTopNCells(1),
        then this object contains the atmMatrixSDCells delta cell
        rate for the reverse direction traffic (i.e., destination to
        source traffic). |
